Filed: 1998-09-15
Abstract: PURPOSE: A method for forming the trench isolation of a semiconductor device is provided to prevent a dislocation and a crack generated in an active region when forming a trench isolation on a semiconductor substrate. CONSTITUTION: By a method forr forrming the trench isolation for a semiconductor device, the stress on an active region is minimized when forrming a trench isolation. A trench(110) is forrmed by etching a part of a semiconductor substrate(100) using a mask pattern forr trench isolation forrmation as a mask. After forrming a third insulation film along both sides and a bottom surface of the trench, a second insulation film on both sides of the trench is removed by wet etching process. A passivation film(114) is forrmed to be rebounded a first and the third insulation film with a material capable of absorbing the expansive forrce of the semiconductor substrate and a trench filling material. Then, after a trench isolation film is forrmed to fill the trench fully, the trench isolation film and the passivation film are etched flatly until a top surface of the first insulation film on both sides of the trench is revealed and the first insulation film is removed. The stress is dispersed since the corner part and the top part of the bottom surface of the trench is rounded by forrming the passivation film after forrming a thermal oxide on both sides and on the bottom surface of the trench, and the method prevents the stress from transferring to the active region by absorbing the expansive forrce of the trench filling material and the semiconductor substrate during high temperature process.

Abstract: A chemical mixing system for mixing ultra pure water and concentrated HF to a desired concentration within a qualification range. Batches of the mixed chemical are mixed in a relatively small mix vessel and transferred to a relatively large mix drum. The concentration of the chemical within the mix drum is measured by a concentration monitor. If the measured concentration of the chemical in the mix drum is within the qualification range, the batches of chemical in the mix vessel are mixed to the desired concentration. If the measured concentration of the chemical in the mix drum is below the qualification range, the batches of chemical in the mix vessel are mixed to a high concentration which is greater than the desired concentration. If the measured concentration of the chemical in the mix drum is above the qualification range, the batches of chemical in the mix vessel are mixed to a low concentration which is less than the desired concentration. Batch averaging is thereby performed to maintain the concentration of chemical in the mix drum within the desired qualification range.
